This invention relates to card perfor-ating or punching machines adaptedfor use in connection with the perforated card tabulating art. In thisart, data is applied toV record s cards by perforating the card incertain posii5 the keys for selecting the punch for operation and for atthe same time closing an electric circuit through an electro-magnet. Theenergization of the magnet then operates the selected punch to perforatethe card.

go Inl the Apresent invention I have provided a'n electric motorwhichmay be in constant rotation while the punch is being used. Thismotor Ioperates 'an actuator which vwhen a punch-selecting key isdepressed quickly actua'tes the punch, after which the partsimmediatelyreturn to normal position, leaving the machine in readinessfor the next key depression.A i p i Y a One of the objects of thepresent invention 80 is to devise a punchingv machine in which greaterpower is available for forcing the punch through the card so that it maybe possibleJ to perforate several cards at once.

Another object is to provide a machine which may be Operated withgreater speed than is at present possible.

In the aforesaid co-pending application, when apkey is depressed alockingdevice pre-Y vents depression of other key until the depressedkeyhas returned to normal position'.` In' the present invention when a keyis depressed an'd the motor forces the punch through 'the card thelocking'r device immediate'y releases' the' parts so that the next keymay their be (repressed betere the previously depressed key hasreturned' to* normal posi'- tio'n'. This permits greater speed inoperation.

Referring te are draw-inge wit-teinr have shown what I now consider tobe the preferred form yof my invention:

In the drawings the machine is shown as comprising a base portion 1along which a card 2 is adapted to be fedbeneath a row of punches 3. Themeans for feeding the card may be similar to that shown in the aforesaidSchaaff application and will, therefore, not be disclosed in detailhere, it being suflicient to point out that the spring driving gear 4meshes with the ,rack 5 which is provided With ratchet teeth Gfcooperating with the escapeinent pawls 7 and 8. The punches 3 aremounted in an upper guide support 9 and lower guide 10v and are adaptedto be depressed into the die member 11, the card 2 being in positionbetween the members 10 and 11. A The punches are provided with springs12 for returning them to normal position after they have been depressed.Above each punch is an yinterposer bar Y13 guided `at the left hand endby a member 14 and at the right hand end by a. member 15. .Eachinterposer 13 carries a pivoted bracket 16 held by a spring 17 normallyin the position shown in Fig. 1 with the lateral stopf l18 resting onthe topv of the interposer. A bell crank 19 pivoted at `20 to the uppercasing21` of the machine is adapted to'be actuated by depression of thekey 2,2, a spring 23 being provided to return the key to normalposition. A spring 24 connected to the' member 1&5" and to theinterposer 13' is adapted t normally hold the interposer in its normallyinoperative position toward the right as shown in Fig. 1, also holdingthe left hand end of the interposer in its upper position against theguide 14. Adjacent to the ends of the several interposers 13 is anactuating ratchet bar 25 having projections 26. rIhe said bar isprovided with a, shaft 27 fixed thereto. The said shaft is mounted inbearings 28 for rotation and is provided with a worm wheel 29 meshingwith a spiral gear 30 mounted on shaft 31. Said shaft in turn has a wormwheel 32 meshing with a` worm 33 on the shaft of the driving motor 34.When the machine is being used the motor is in constant operation andcauses the bar 25 to rotate. lVhen any one of the keys 22 is de pressedit moves the corresponding interposer bar 13 from the position shown inFig. 1 to that of Fig. 2, thus moving the interposer into cooperationwith the actuating bar 25. The bar 25 thus depresses the interposer 13and this in turn depresses the punch 3 to perforate the card. I/Vhen theinterposer 13 is depressed its bracket 16 is carried below thecontacting point of the bell crank 19 so that the interposer will thenbe free to return to normal position under the infiuence of spring 24. Acam 35 which is here shown as being integral with the punch guide 9 mayalso be provided so that when the actuator 25 depresses the interposerthe latter will engage the cam and be positively withdrawn from theactuator. The cam, however, is not essential. At the right hand end ofthe interposers are shown the inter-locking elements 36 which preventmore than one interposer moving to operative position at a time. As soonas the bracket 16 escapes from the bell crank 19, permitting theinterposer to be returned to normal position as shown in Fig. 5, theinter-locking elements 36 are then in position to permit anotherinterposer to be actuated before the key 22 has returned to its upper ornormal position. Thus when an operator depresses a key he is able toquickly depress the next key without waiting for the previouslydepressed key to reach its normal position.

In Fig. -6 I have shown a modified connection between the operating key22 and the interposer bar 13. In this form, instead of the springpressed bracket 16, I have shown a fixed pin 16a. Also the bell crank19a in this instance is connected to the frame 40 by means of a pin andslot connection 41 to the bracket 42. A spring 43 normally holds thebell crank in its lowermost position. When the key 22 is depressed thebell crank 19a engages the pin 16a and moves the interposer 13 to theleft as in the case disclosed in Fig. 2. When the interposer isdepressed so that the pin 16a moves out of cooperation with the bellcrank 19a the interposer is carried back to normal position as shown inFig. 6. The parts are then in the position indie-ated in this view. Newwhen the key 22 is released its spring 44 returns it to normal position.The bell crank 19a then rides over the top of the pin 16a, the spring 43permitting the bell crank to rise on its pin and slot connection 41until it passes over the pin 16a and drops down into position ready tobe operated again. The spring 44 is stronger than spring 43 and also hasa much greater leverage in acting upon the bell crank 19a so that thereis no difficulty in forcing the spring 43 to yield to permit the bellcrank 19a to ride over the pin 16a.

In Fig. 7 I have shown a modified connection between the actuating bar25 and the motor 34. In this case the worm 33 on the shaft of the motoris connected directly to the worm wheel 29 on the shaft 27 of operatingbar 25. In this instance the motor is placed directly behind themachine, Whereas in the form shown in Figs. 1 and 4 the motor may beplaced in the base of the machine.

As shown in Figs. 1 and 2 the carriage escapement pawls 7 and 8 areadapted to be actuated whenever any one of the keys is operated by meansof the bail 45. This bail is mounted below the several interposers 13 sothat whenever any one of them is depressed the bail 45 is rocked andpermits the escapement mechanism to operate to feed the card one step tothe left in the manner disclosed in the aforesaid co-pendingapplication.

I-Iaving described my invention, what I claim and desire to secure byLetters Patent is:

1.
